The 49ers punt returner said he is "shocked" the Giants weren't punished by the NFL for targeting him in last year's NFC Championship Game. "The only thing crazy to me was that nothing came of it after they came down so much on the Saints," Williams said. What Giants special teamers Jacquian Williams and Devin Thomas said after New York's 20-17 overtime victory sounded similar to what the Saints were sanctioned for. "The thing is, we knew he had four concussions, so that was our biggest thing was to take him out of the game," said linebacker Williams, who forced the 49ers returner's overtime fumble, which set up the winning field goal. Thomas recovered both errors - the first was considered a muff when the ball glanced off Williams' right knee. "He's had a lot of concussions," Thomas said. "We were just like, 'We've got to put a hit on that guy.' " Kyle Williams will miss Sunday's game with an injured left knee.

The three-time MVP is returning to the NFL - to work for the NFL Network. Favre will join the network for daylong coverage of Sunday's game. "I don't miss the grind and stress of day-to-day football, but I do miss my teammates and coaches," Favre said. He chose to appear on "NFL GameDay Morning" because he could work with friends such as Steve Mariucci, Deion Sanders and Warren Sapp. "Players and coaches who I have great memories of, and to do it from the field where I won a Super Bowl was a tough combination to pass up," Favre said. "Between my appearance on NFL Network and my work with Virtual Fan Network, a new digital sports marketing company, it will be great to reconnect with NFL fans around the Super Bowl."
